Summary

CVE-2023-44390 is a vulnerability that affects the HtmlSanitizer library in .NET. It specifically occurs when foreign content, such as `svg` or `math`, is allowed in the configuration. In vulnerable configurations, an attacker can bypass input sanitization and inject arbitrary HTML, including JavaScript code. However, this vulnerability is not present in the default configuration. The issue has been fixed in versions 8.0.723 and 8.1.722-beta of the library. The potential danger to organizations is that it can lead to cross-site scripting (XSS) attacks, which can compromise user data and enable unauthorized actions on affected systems.
